The Skirball Cultural Center in Los Angeles will host the first comprehensive exhibition on legendary music promoter Bill Graham. Billboard reports that “Bill Graham and the Rock & Roll Revolution,” which is set to run from May 7 to October 11, will feature memorabilia, photographs, archival concert footage, new and old interviews, letters from performers and fans, psychedelic art from the San Francisco scene and more.

The exhibit will include a number of items on loan from the Graham family, along with the original apple barrel that greeted fans at the entrance of the famed Fillmore Auditorium. Liquid light show pioneer Joshua White (The Joshua Light Show) will also be creating a customized version of the backdrop he produced for many of Graham’s shows.

In addition to music memorabilia, the exhibit will also showcase how Graham’s early years as a Jewish emigrant influence desire to promote social justice at benefit concerts like Live Aid 1985 and Human Rights Now!

The exhibit is taking place this year to coincide with the 50th anniversary of Graham’s first concert—a fundraiser in support of a member of the San Francisco Mime Troupe—as well as the 50th anniversary of the first performance by the Grateful Dead, who famously developed a long-running, fruitful partnership with the Graham.

Graham died in a helicopter crash in 1991. He was 60 years old.
